GATE

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application led August 27. 1907 Serial No. 390,288.

To all whom it may concern: j

Be it known that I, ADOLF E. AEsoHLr- MANN, residing at Taylor, in the county of Villiamson and State of Texas, have invented certain new and useful lmprovej ments in Gates, of which the following is a j specification.

My invention relates to certain new and useful improvements in gates of the verj tically opening balanced type and it pri-j marily has for its object to provide a gate of this character of a very simple-and eiiective j construction, which can be easily and cheaply manufactured and which will readily andA effectively serve its intended purposes.

ln its generic nature, my invention comj prises a gate consisting of two sections mounted in posts at the sides of the road and adapted to open and close from and toward one another, the sections being adapted to be folded when in their open position, and means are also provided for locking the sections both in their open and closed positions, and means lor iirst releasing the locking device and then tilting the gates on their fulcrums to open or close the same, as the case may be.

My invention also includes a positive connection between the tilting lever and the j gates whereby the motion of the tilting lever will be simultaneously imparted to each oi the gate sections,

In its more specii'ic nature, the invention embodies certain novel constructions, comn j binations and arrangement oi'l parts all oi'l j which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure l, is a perspective view showing my invention with the gate closed. Fig. 2, is a side elevation oi a modified form oi' my invention, the gate being in its closed position. Fig. 3, isa detail perspective view showing the locking mechanism. Fig. 4, is a similar view showing the means for securing the two gates at their points of juncture. Fig. 5, is a detail perspective view of a modiiied form of j my invention. Fig. 6, is a perspective view j of the form of my invention shown in Fig. l, j the gate being open. Fig. 7, is a side elevation of the form of my invention shown in j Fig. 2, the gate being open.

Referring now to the accompanying drawings, in which like letters and numerals of reference indicate like parts in all of the iig.- ures, l designates the main supporting posts which are adapted to be sunk into the ground to a satisfactory depth at each side of the road, and to which the gate posts 2 are bolted, or otherwise secured, as at la, the posts 2 being formed of parallel bars 2a between which the gate sections 3 and 4 are fulcrumed. One of the gate posts 2 is eX- tended upwardly to a greater height than the other and is connected at the top by a spacing block 2b having a bearing portion 2C to which the gate operating lever 5 `is fulcrumed, as at 5a in a manner which will be clearly understood by referring to the drawings.

Cilach gate section comprises parallel hori- Zontal'bars 3aL and 4a, connected at their adjacent ends by the central abutting bars 3b and 4b respectively which posts are formed of a pair of parallel bars pivotally secured to the horizontal bars 8a and 4ft by bolts 8 and 4? respectively, as shown. The bar 4b is provided with a spring metal locking member 4d which is adapted to have its end 4e projected over the top 3d of the bar 3b to lock the bars 3b and 4b together, guard members 4f being provided on the bar 4b and embracing the post 3b to prevent the locking member 4d becoming ammed and inoperative. On long gates intermediate vertical supporting bars 3g and 4g respectively may be provided, as shown in modification, Fig. 2, and these bars are pivoted to the horizontal bars 3a and 4a respectively, in a manner similar to that of the posts 3b and 4b.

3m and 41 respectively designate metallic bearing clips which are secured to the horizontal bars 3ZL and 4a respectively of the gate sections 3 and 4, and through which the pivot bolts 2m which project through the posts 2,

pass and thus pivotally connect the gate sections 3 and 4 with the posts 2, it being understood that all the bars 3 and 4aof the respective gate sections 8 and 4 are parallel as are also the posts 2, bars 3b`4b and the bars 3g and 4g, when such are used.

, 6 designates foot members which may be the lower ends of the bars 3b and 4b or they may be in the nature of metallic members secured to the lower ends of said bars, and having their lower portions diverging to rest upon the V-shaped or beveled upper surfaces 7 a of a center block? which is adapted to be sunk into the ground midway between the posts 2 and only have its upper surface 7a j exposed. 8-8 designate bearing clips secured to the respective bars 2CL of the posts 2 in which the upper bars 3LL and 4 of the gate sections 3 and 4 respectively arefulcrumed instead of j being fulcrumed directly to the posts 2. T he i bars 3 and 4lL have projecting members 9 l which diverge at their outer ends carrying counterweights 1() to counterbalance the gate sections 3 and 4.

11 designates a latch member fulcrumed at 11"1L to the upper gate bar 4u of the gate section 4, and provided with notches 11b and 11C respectively which are adapted at times, to engage with the locking bar 1lLL of a U- shaped locking member 12 that is secured to the post 2 and which locks the gate section 4 l so as to hold the gate section 4 either in its open or closed position, as the case may be.

13 designates a latch releasing member which is endwise slidable in bearings 14, carried by thepost 2 and is normally spring pressed out of engagement with the latch 11 by a spring 13" which is mounted on the member 13, as clearly indicated in Fig. 3, of the drawings, the member 13 having a passage 13" for the end of the latch 1,1. T he latch release member 13 has a projection 13 that passes through a slot 12m in the member 12 and is furthermore provided with a finger j 13m which engages the underside of thc latch 11. rFliese parts are shown particularly in l Fig` 3 of the drawings, parts thereof being broken away to more cleariy show the engagement between the latch 11 and the member 12.

The operating lever 5 which is pivotally mounted at 5fL at the top of the post 2, as before stated, carries a double bell crank lever 15 which has its horizontal portions 15All connected with the member 13 by wires or ropes 16, or in any other manner desired. Each end of the lever 5 is slotted as at 5X, to receive the bell crank levers 16h, which are pivotally mounted at 16 therein and are connected with the centrally mounted double bell crank lever 15 by ropes or cables 17, as shown. Pull ropes or cables 18 are connected to the other ends of the bell crank levers 16b and are adapted to be engaged by the operator when it is desired to manipulate the gate.

19 designates a tubular casing which is mounted in apertures in the posts 1 and the center block 7 and projects from one post 1 to the other through the center block 7 and this casing 19 may be, in practice a two inch pipe in which the gate operating shaft 28 is mounted. r1he shaft 20 may be also con-l structed of pipe material of lesser diameter than that of the casing 19 and at one end the shaft 20 carries a sprocket wheel 21, around which a short chain section 22 passes, the chain section 22 being connected by rods or l cables 23 to the operating lever tances from the fulcrum thereof. other end the shaft 2() is provided with a crank 23 which is connected by a pitman 24 with the extension 9 in the gate sections 3, while the sprocket 21 also has a crank portion 23b which connects with the extension arm 9 of the gate section 4 through the medium of a pitman 24a, as shown.

Instead of constructing my improved gate in the manner just described, which is the preferable construction for a wooden gate, 1 may make the same of metal', as shown in Fig. 2, of the drawings, by reference to which it will be seen that the various bars of the gates are formed of pipe sections, otherwise 5 at equal disthe construction of this form of my invention is substantially the same as the other form with the exception that the extensions 9 are each made of one pipe section `on which the weights 10 may be adjusted along the same by a set screw .10, as shown. In both forms of my invention, as shown in Figs. 1, 2, 6 and 7, 1 may use wires 25, either barbed or plain, but for convenience of illustration, I have simply indicated such wires as plain wires and indicated them on Figs. 2 and 7 of the drawings. The gate shown in Figs. 2 and 7 may be made either of plain pipe or made ornamented, as such ornamentation forms no part of my present invention.

So far as described, the manner in which my invention operates, will be best explained as follows i-issume the parts to be in the position vshown in Fig. 1 and it is desired that the gates be opened to permit passage therethrough; the operator grasps the hand engaging portion of the pull rod or cable which rocks the bell crank levers carried by the lever 5 and causes the motion thereof to be imparted to the latch raising member 13, which raises the latch 11 out of engagement with its locking bar 12, and as the operator continues pulling, the tilting of the bar 5 will turn the shaft 20 and cause the cranks to impart such motion through the pitmen connections to the gate sections 3 and 4, rocking them on their pivots and raising the gates to the position shown in Figs. 6 to 7. As the gates reach their open position the notch 11b of the latch 11 will engage the member 12a and lock the gates in their open position, it being understood that when the gate section 4 is locked by the latch 1l, no motion can be imparted to the gate 3 since it is held rigid through the medium of the shaft connection 20 and the pitmen which connect the shaft 20 with the gate sections. After passing through the gate,lhowever, the operator grasps the pull cord or rope at the other end of the lever 5 and pulls down on the member 6, causing the latch member 13 to release the latch 11 and permit the gates to be swung to their closed position as the bar 5 is again brought to its normal or horizontal position. It should 'be At the t stated that the latch releasing member V13 is preferably provided with a notch 13X for the latch 11, as shown.

In Fig. 5, I have shown an enlarged detail of a portion of the gate shown in Figs. 2 and 7, and showing the manner of connecting the pipes 3 to the vertical pipes forming the abutting ends of the gate.
